As the touch sensing devices are getting thinner (fewer or thinner substrates) and capacitive touch sensing technologies are getting implemented in a growing number of new environments, new challenges arise for touch sensor designers. One major challenge is to provide proper EMI (Electromagnetic interference) immunity levels to touch sensors. Providing proper EMI immunity can be aRead more

One of the parameters that engineers have to know in order to properly configure the controller is called ‘Charge Phase’. Tuning the Charge Phase parameter can be done in different ways. In this post, we will show how simulation can help identify the ‘Charge Time’ values of the sensor that are used to properlyRead more
An industrial touch screen display enclosure serves one purpose… to protect your touch screen computer equipment used in heavy-duty work areas. An industrial touch screen enclosure solution stops liquids, dust, heat, humidity and more from damaging your touch panel. However, its one purpose provides many benefits. Industrial touch screen display enclosures provide more than protectionRead more
Electrodes are the backbone of capacitive touch sensors. So, the behavior of touch sensors heavily depends on the materials electrodes are made of. Despite this well known fact, for a long time engineers overlooked experimenting with different transparent electrode materials. The default option of Indium Tin Oxide (ITO), which dominated the market for a longRead more
And He has Shaken – Not Stirred- the Touch Screen Industry. What is this Optical Bond you’re talking about? Optical bonding is one of the methods of attaching (gluing) a protective cover glass with a touch screen or touch sensor. Optical bonding has gained popularity due to its advantages over the previous, most popular choice:Read more
